AD9562

The AD9562 is designed as one kind of highly efficient synchronous buck switching regulator controller optimized for converting the 5 V main supply into the core supply voltage required by the Pentium III and other high performance processors. This device can be used in (1)Desktop PC Power Supplies for:; (2)Pentium II and Pentium III Processor Families; (3)AMD-K6 Processors; (4)VRM Modules.

Features of the AD9562 are:(1)active voltage positioning with gain and offset adjustment; (2)optimal compensation for superior load transient response; (3)VRM 8.2, VRM 8.3 and VRM 8.4 compliant; (4)5-bit digitally programmable 1.3 V to 3.5 V output; (5)dual N-channel synchronous driver; (6)total output accur-acy 61% over temperature; (7)high efficiency, current-mode operation; (8)short circuit protection; (9)overvoltage protection crowbar protects microprocess-ors with no additional external components; (10)power good output; (11)SO-16 package.

The absolute maximum ratings of the AD9562 can be summarized as:(1)input supply voltage (Vcc):-0.3 V to +16 V;(2)VID0VID4, SD, PWRGD, CMP, CT:-0.3 V to Vcc;(3)DRIVE1, DRIVE2, SENSE+, SENSE:-0.3 V to Vcc;(4)operating ambient temperature range:0°C to +70°C;(5)junction temperature range:0°C to +150°C;(6)storage temperature range:-65°C to +150°C;(7)lead temperature (soldering, 10 sec):+300°C.
